UNITED STATES EDWARD COLLINS, OF NEW YORK, N. Y.

IMPROVEMENT IN DEVICES FOR LUBRICATING CAR-AXLE JOURNALS.

.Specification forming part of Letters Patent No. 118,691, datedSeptember 5, 1871.

To all whom it may concern.-

Be it known that I, EDWARD COLLINS, of New York, in the county of NewYork and State of New York, have invented a new and useful Improvementin Device for Lubricating (Jar- Axle Journals; and I do hereby declarethat the following is a full, clear, and exact description thereof,sufficient to enable those skilled in the art to which my inventionappertains to make and use the same, reference being had to theaccompanying drawing making part of this specification, and to theletters and figures marked thereon.

The nature of my invention consists in: First, a lubricating roller,covered with felt or cloth, suspended in spring bearings, which areplaced in sockets made in curved hangers depending from the bearings.Second, the curved hangers attached to the hearing by dovetailed jointsor otherwise, and serving as bearings for the lubricating roller.

In the accompanying drawing, Figure 1 is a side elevation, partly insection, taken in the line a: w of Fi 2. Fig. 2 is a view of the outerend, the casin g partly broken away to show the interior. Fig. 3 is apartial central sectional view taken in the line 2 z of Fig. 4. Fig. 4is a transverse section through the line 3 y of Fig. 3.

A represents the casing; B, a part of a caraxle; O, the journal; D, thehinged lid to the box 5 E E, double dust-excluding packings, fittingsnugly around the shoulder on the journal. F is a key for holding thebearin g G more firmly against the periphery of the journal, whichseveral parts, being of any desired construction, need no furtherdescription. Curved hangers, a a, are secured to the bearing G bydovetailed joints, as seen in Figs. 1 and 2. They are preferably curvedin the manner shown, and embrace the journal. In their lower ends a asockets are made to receive coiled or other springs, (see Fig. 3,) uponwhich loose bearings b I) rest, the said bearings receiving the gudgeonsof a roller, H. This roller H is covered with a soft, fibrous absorbentcloth or felt, and is so hung in its elastic bearings as to always presslightly against the journal. From the gudgeons of the roller H, andpartially surrounding it, is suspended a metallic box, 0, provided withpartitions orflanges projecting upward from its bottom, as shown in Fig.1, which box receives the oil to be supplied to the roller. By providingthe partitions in the box 0 the oil is prevented from acquiring too muchlateral motion, and is more evenly and better distributed over theroller C, and consequently the journal is kept in better order. Insteadof this box 0, the oil may be simply placed in the axle-box, as at d,Figs. 3 and 4; and in order to prevent splashing and waste of oil afloat, e, is placed over the oil, between it and the roller, an openingor slot being made in the float sufficiently large to allow a portion ofthe roller to communicate with the oil, and thus obtain a full supply.

As will readily appear, as the axle revolves the contact of the rollerwith the journal causes the roller to revolve, and thus supply fresh oilto the journal. continuously, and at the same time prevents it fromclogging or massing on the journal, a sufiicient degree of heat beingconstantly generated to keep the lubricant soft.

In order to more effectually exclude dust, sand, 850., from thejournal-box, I provide a double packing, E E, which at the same timeeffectually prevents the escape of oil from the journal-box, thusserving a twofold purpose.

Thus constructed, a lubricating axle-box is produced whose manyadvantages will readily appear to those conversant with the art to whichit appertains. It is simple, not liable to get out of order, and iseffectual in operation, excluding dust, 820., from the box, andpreventing waste of oil, and keeping the journal constantly lubricated.

What I claim as new, and desire to secure by Letters Patent, is

1. The roller H, covered with cloth or other lubricant-absorbingmaterial, and suspended in spring bearings, b, which are placed insockets made in the lower ends of curved hangers a a, depending from thebearing Gr, constructed and arranged and operating in combination withthe journal, substantially in the manner and for the purpose shown anddescribed.

2. The curved hangers a a, secured to the hearing Gr by dovetailedjoints or otherwise, and serving as bearings for the lubricating roller,substantially in the manner and for the purpose shown and described.
